Bisexuality?
As noted above, Emperor Wen greatly favored Deng Tong, for no particular apparent reason, and he gave Deng much honor and wealth despite Deng's apparent lack of ability. This, coupled with later references by officials trying to persuade Emperor Ai against giving his male lover Dong Xian too much authority—during which those officials analogized Dong's position to Deng's—has led to speculation that Emperor Wen had a homosexual relationship with Deng. It is quite possible, but also hardly proven based on available evidence. In 162 BC, Emperor Wen permitted the prime minister Shentu Jia (申屠嘉) to discipline Deng for his arrogance and threaten him with death, before pardoning Deng. In Emperor Wen's request to Shentu asking Shentu to be lenient with Deng, he called Deng his "jester."
